javascript - NodeJS、Javascript 聊天；对于每个数组

Question

NodeJS 脚本:

var rooms = [];

rooms.push({
    from: 'Chat-o-matic',
    allowedFor: 'everyone',
    name: 'Openbare kamer'
});

socket.emit('sendRooms', { value: rooms });

客户端JS:

function buildChat() {
    console.log("Build chat...");
    var rooms = [];
    socket.on('sendRooms', function(roomsocket) {
        console.log("Loading rooms...");
        roomsocket.forEach(function(data) {
            console.log(data.from);
        });
    });

    console.log(rooms);
    $( "#container" ).html("");
}

我想显示来自数组房间@服务器端的每个“来自”，但现在我在客户端收到此错误:

Uncaught TypeError: Object # has no method 'forEach'

我做错了什么？又该如何解决呢？

Answer 1

您正在发出一个对象。我猜你想迭代值，这是一个数组:

roomsocket.value.forEach(function(data) {
   console.log(data.from);
}):
